Mitosis and Meiosis Review Flashcards
1
Q
What does G2 of interphase look like?
A
- Duplicated chromatin in nucleus
- Centrosomes together
2
Q
What does prophase look like?
A
- Early mitotic spindles form
- Centromeres begin to form
- 2 sister chromatids combine to form chromosome
3
Q
What does prometaphase look like?
A
- Kinetochores keep sister chromatids attached
- Nuclear envelope has broken down
- Centrosomes move to opposite ends
4
Q
What does metaphase look like?
A
- Homologous pairs line up in middle (metaphase plate)
5
Q
What does anaphase look like?
A
- Chromatids are pulled apart to form daughter chromosomes
6
Q
What does telophase/cytokinesis look like?
A
- Cleavage furrow (pinch in centre of cell)
- Nucleolus forms
- Nucleus envelope forms
7
Q
What is the function of a human karyotype?
A
- Used to assess genetic health at a chromosome level
8
Q
What are the basics of mitosis?
A
- Double DNA and split cell
- Homologous pair is formed after doubling
- Diploid -> diploid (exact copy)
9
Q
What are the basics of meiosis I?
A
- Segregate homologous chromosomes
- Creates diploid cells
10
Q
What are the basics of meiosis II?
A
- Separate sister chromatids (like mitosis)
- Creates 4 haploid gametes
